Ms. Morgan is a science teacher. She found that 30% of her 120 students are athletes.
Mr. Gregory is a math teacher. He found
that 27, or 15%, of his students are athletes.
a. Of the part, the whole, and the percent,
which information is still unknown to
Ms. Morgan? Find this unknown value.
b. Of the part, the whole, and the percent,
which information is still unknown to
Mr. Gregory? Find this unknown value.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to
